Description

technical field [0001] The present application relates to the field of wireless communication, and in particular, to a method and a receiving device for adjusting a processing algorithm of a wireless communication network. Background technique [0002] The wireless signal processing of long term evolution (LTE) is mainly responsible for the physical layer and the medium access control (MAC) layer. The physical layer is responsible for the modulation and demodulation, coding and decoding, channel estimation, and channel equalization of the electromagnetic wave signals of different frequencies on the wireless air interface. The MAC layer is responsible for scheduling the modulation order of the modulation method and the channel coding rate according to the signal to interference plus noise ratio (SINR) and block error rate measured by the physical layer of the receiving end. The MAC layer schedules higher modulation order and channel coding rate for users with lower SINRs, an...

[0004] However, when the modulation order and channel coding rate are too high, using the SINR with higher historical measurement results actually wastes the algorithm performance of the physical layer at the receiving end in channel estimation, channel equalization, demodulation and decoding, and vice versa. When the modulation order and channel coding rate are too low, the SINR with low historical measurement results may not be able to obtain the correct value through the processing algorithm at the physical layer of the receiving end, which makes the processor set at the physical layer of the base station Processing performance cannot be further improved
